About Wave Height
I am a recent user of DualSPHysics and I have a question that has arisen as I use it.
I have generated regular waves using Piston, and I would like to know why there is an error between the input wave height and the wave height measured using wg.
As for dp, it is set to wave height/10.
I would like to know. Thank you in advance.

Can you please share with us your results? so that surface elevation at 6 meter from piston using SPH and theory?
Hi Alex, I'm looking forward to hearing from you.
Thank you for your reply.
Please find attached the results for your confirmation.
The wave height was measured at 6.24m.
I also have two additional questions.
1. You specified a height of 6m from the piston, why 6m?
2. When I look at the resulting graph, not only do the wave heights not appear to be in line with the input, but they also appear to be damped.
I am concerned that the attenuation is given, but that it is slowing down much earlier than that.
I would appreciate an answer to both of these questions.
Dear user
I am looking into your problem
but regarding your question: "You specified a height of 6m from the piston, why 6m?"
I do not know what you mean?
I have created your case, and I do not understand what is your objective....
You have created a 3d rectangular tank of more than 15 m....
You are creating waves of H=0.15, T=1s, depth=0.66 so that L=1.5
And you are computing wave elevation at 6 meters fro the piston... so that 4 wavelengths
Can you explain what are you simulating? and the objective?
Thank you for your response.
To your question about what was the purpose of the simulation.
I recently started using DualSPHysics and wanted to know the characteristics of this software.
So I ran the simulation to see if the input and output values would match when the wave was generated by the piston.
I am very sorry for the trouble, but I would appreciate your response.
